Sample text

As before, the system objects are points in a multi-dimensional phase-space. , etc. Object-oriented systems lend themselves easily to this interpretation. In fact, the objects of interface editors such as HyperCard and Supercard are defined as a bundle of more than 100 properties. Programming such systems means to define the force-field and the boundary through which the user can disturb the field. The idea is elaborated in Andersen 1992b, 199»4a, 1995, and has been used in practice to construct a multimedia system about the Viking age that is currently running in a Danish museum.
